Police said security took the man out of the club through the back door and escorted him to the front. After a fight broke out, the suspect allegedly took out a handgun and began shooting, killing Spears around 2 a.m. Sunday.

Some on social media were horrified by the news.

Mary Spears died for not giving a man her phone number. This is every woman's nightmare. http://t.co/5iwRGIANRg
